WARNING: The QUIESCE option of the CSUSPEND command has been
disabled by APAR OW15247 or APAR OW15248. Refer to either of these APARs
and the latest IBM PPRC documentation for detailed information on the
QUIESCE option of the CSUSPEND command. Please check with your Hitachi
account team before using the CSUSPEND command with the QUIESCE option
to suspend TCz pairs on USP V storage systems. If the CSUSPEND command
with the QUIESCE option is issued to certain volumes (e.g., active SPOOL,
PAGE, or CATALOG datasets, active SYSRES volume), the attached host(s)
may enter a deadlock condition and may require a storage control IML to
correct the condition. TCzA does not support the CSUSPEND/QUIESCE option.
